Which of the following are known quantities for this electromagnetic wave? Check all that apply. Check all that apply. amplitude of the electric field amplitude of the magnetic field direction of the electric field direction of the magnetic field

amplitude of the electric field amplitude of the magnetic field

Explanation:

Electromagnetic waves are waves which are developed as a result of vibrations between an electric field and a magnetic field. There are different types of electromagnetic waves which includes:

- radio waves, microwaves, infrared waves, visible light rays, gamma rays, x- rays and ultraviolet waves.

These electromagnetic waves moves in a direction that is at right angles to the vibration of both the electric and magnetic field, that is, the two fields are mutually perpendicular. All forms of electromagnetic wave share fundamental wave - like quantities which includes:

- Wavelength, frequency, amplitude.

Amplitude is simply defined as the intensity or maximum field strength of electric and magnetic fields.

thermal energy is the answer
